Ice or water do nothing for me....sometimes hard candy helps me. There are these specialty things...I think they are over in the mouthwash isle...its like a spray...you can get. Also they have some maybe glycerin lozenges...same principle.

With the possible Sjorgens go check out that spray and lozenges. I cant think of the exact name but if you search around you will find them. They are specifically made for dry mouth.
